In the coming years, NASA plans to send several astrobiology missions to Venus and Mars to search for evidence of extraterrestrial life. These will occur alongside crewed missions to the Moon (for the first time since the Apollo Era) and the first crewed missions to Mars. Beyond the inner Solar System, there are ambitious plans to send robotic missions to Europa, Titan, and other “Ocean Worlds” that could host exotic life. To accomplish these objectives, NASA is investing in some interesting new technologies through the NASA Innovative Advanced Concepts (NIAC) program.

This year’s selection includes solar-powered aircraft, bioreactors, lightsails, hibernation technology, astrobiology experiments, and nuclear propulsion technology. This includes a concept for a Thin Film Isotope Nuclear Engine Rocket (TFINER), a proposal by senior technical staff member James Bickford and his colleagues at the Charles Stark Draper Laboratory – a Massachusetts-based independent technology developer. This proposal relies on the decay of radioactive isotopes to generate propulsion and was recently selected by the NIAC for Phase I development.
